Prior to 4.12.18, improper validation of the JWT NumericDate claims exp, nbf, and iat in hono/utils/jwt allows tokens with non-spec-compliant claim values to silently bypass time-based checks. This issue is not exploitable by an anonymous attacker; it only manifests when a malformed claim value reaches verify() — typically when the application itself issues such tokens, or when the signing key is otherwise under attacker control. This vulnerability is fixed in 4.12.18."},{"lang":"es","value":"Hono es un framework de aplicación web que proporciona soporte para cualquier tiempo de ejecución de JavaScript. Antes de la 4.12.18, la validación indebida de las reclamaciones NumericDate de JWT exp, nbf e iat en hono/utils/jwt permite que los tokens con valores de reclamación que no cumplen con la especificación omitan silenciosamente las comprobaciones basadas en el tiempo. Este problema no es explotable por un atacante anónimo; solo se manifiesta cuando un valor de reclamación malformado llega a verify() - típicamente cuando la propia aplicación emite dichos tokens, o cuando la clave de firma está de cualquier otra forma bajo el control del atacante.
